To all whom t may concern.' y

Be it known that I, FRITZ AL. CARLSON', a citizen of the United States,residing at Kansas City, in the county oflVVyandotte and State ofKansas, have invented certain new and useful Improvements in'Convertible Furniture, of which the following isa specifl fication.

,This invention relates to convertible fur-7 niture, and particularly toconvertible swings, having for its primary ob] ect to generally simplifyand improve the construction and operation of devices of this characteras well as to increase their efficiency.

'A further object of the invention is` to provide a convertible swing ofthe character mentioned which may be very quickly and easily changedfrom a swing to a bed, and which is equipped with improvedmeans forholding the movable parts of the apparatus in proper position. y

A still further object of the invention is to provide a device of thecharacter men tioned which is equipped with changeable seat and bedportions, and with which is associated an improved means for holding theseat portions in proper positions. c

Still further objects of the invention reside in providing aconvertibleswing which shall be of extremely simple and inexpensiveconstruction, which is composed of but few readily assembled parts, allso constructed and arranged as tominimize the `opportunity for wear orbreakage, which 'may be very quickly and easily converted from a swingto a bed, and which will tical and efficient. y Y

TWith these objectsrin view, together with others which will appear asthe description proceeds, the invention resides in the novel formation,combination, and arrangement of parts, all as will be described more`fully hereinafter, illustrated in the drawings, and particularly pointedout in the claims.,

ln the drawings Figure 1 is a side elevation of a convertible swingconstructed in accordance with the invention,` the view illustrating thedevice/asfit would. appear in being converted into a bed,

Fig. yZis a top plan illustrated in Fig. 1,

Fig. 3 is a longitudinal sectional View taken upon liIieB-B of Q f viewof the device prove highly prac-v ,Figt 4 is a bottom plan view oftheimproved convertible furniture, and

Fig. 5 is a transverse sectional view taken upon line 5-.5 ofFig. 2, andillustratingY particularly the manner in which the bed and back framesare rotated within their respective supporting frames. f

vReferring now more particularly tothe drawings, @indicates a body orsupporting frame, comprising in the present instance a pair ofrelatively short angle bars as shown, from each, of which extendsupwardly side arm supporting framework 7. Thisframework may include apair of upstanding posts 8, supporting at their upper ends an arm restor shelf 9. The framework also includes a pair of upwardly extendingrods 10, lirmly Secured at their lower ends to the angle bars, and eachbeing )rovided in its upper end with an eye or oop l1 within which thelinks of supporting chains 12 are secured.v The chains 12 may be securedat their upper ends to rings 13 in a ceiling, and it is obvious that thebody or supporting frame thus suspended will be capable of swinging.

vvThe body or supporting frame has revolubly mounted therein a bed frameindicated at 14. This bed frame is of a width substantially equal to thelength of the angle bars constituting the supporting frames, and a`pivot pin 15 projects outwardly from each endV lof the bed frame 14midway of the ends of the frame.v The pivot pin 15: at each end ofthebedframe is rotatably supported by the adjacent angle bar G, so that thesaid bed frame is capable of being rotated uponv its longitudinal axis.

In the present instance, the bed lframe 14 is of rectangular shape,constituting longitudinal side rails 16, connected at their exetremitiesby the end rails 17 the pivot pins 15 being. extended through the saidend rails intermediate the extremities thereof, AOne surface of this bedframe is provided with longitudinally disposed kslats 18, while thereverse side of the frame is provided with a spring mattress or cushionsupport 19. VA box spring is shown in the drawings, but it will beunderstood that a woven wire spring may with equal facility be employed.By so constructing the vbed frame, either the slatted surface may bepresented, or the said frame may be turned so'as tojpresent the springsurface.

' The means for holding the body .andbed frames against relativemovement lcomprises a plurality of slidable locking bolts or bars 21,the said loars being adaptedfto lconnect the said frames so as to firmlylock the same against movement. The lockingfbolts are 'boltspass throughlthe, end rails 17 of the bedvframe, and are adapted to enter openl ingsprovided in the depending portion of the'adjacent angle bar of the frame6. Each of the locking bolts has aiiixed'thereto a collar'23,'againstwhich an expansion spring 24 engages, and the said expansionl springsseat 'at their inner ends against the vkeeper bars 22. Thisy springarrangement causes theV locking bolts 21 to be normally projected, sothat when the lbed frame is rotated, the eX- tremities of the lockingbolts will snap into engagement with the adj acont/body frame anglebars. Guide plates 25 may be secured to the angle bars 6 adjacent theopenings therein to receive the extremities of the locking bolts, sothat the locking bolt'ends will be preventedfrom engaging the upper andlower edges of the body frame bar bed frame is rotated. Pivotedintermediate their ends as at 26 at the center of the bed frame 14 are apair of levers 27. These levers are of equal length and each'hasconnected to its oppositeends the inner extremity of one vof the lockingbolts 21. It will be observed. that the ends of theleversare connectedto lockingbolts upon oppositel ends of the bed frame, and isthereforeapparent that rocking movement ofk the'leverlwill cause the said boltsto be withdrawn or projected according to` the direction 4of movement ofthe' said lever.

Slidablyv arranged 'in suitable keepers 28 upon the bed frame 14, at thesides of' the latter, and intermediate .the ends thereof, are operatingrods. 29 for controlling the locking mechanism. .f These rods ,terminateatV their outer ends close to the outer edges of the bed frame 14, andmay be provided with .hand gripsBO Vas shown.v `The inner endsofv therods 29 are each connected to ethe adjacent when the ends of outwardlydiverging links 31, the

latter lbeing provided. adjacent their outer ends with elongated slots82, through which pins 33 secured near the outer ends of the levers 27extend. By-this particular con# struction, it will be obvious thatoutward pull delivered to either of the lock actuating rods 29 willcause the adjacent ends of the links 31l to move outwardly, andthismove'- ment of the links will cause the levers 27 to rlChe i lockingYArear ends of the-rods 38.

rock toward eachother.' This rocking move-- ment yof the llevers causesthe locking bars 21 to be withdrawn from within the apertures in thebody rframe, whereupon the said frame may be rotated. Upon release ofthe operatf.

ing rods 29, the springs 24 will cause the" locking bar .to moveoutwardly, whereupon `the controlling apparatus' for the v,actuatingtion', as indicated by dotted lines in Fig. 1, of

the drawings "This back frame isH also equipped with a bed frame 14,which iscon-v structed and *arranged exactly 'the same as the bedvframeI 14 upon the body frame and which is also equipped with holding orlockn ing mechanismthe saine as that described in connection with Vthebed 'frame 14 upon :the main supporting frame; The hinged back frame 35has secured' at its outer ends the lower extremities of supportingchains 37, the said chains being adapted to 'support the back whenVthellatter is either disposed Yin horizontal or verticalpositions. A

yTo support the back' in uprightposition independently' of the chains`37,- and in such manner as to-.form a vcomfortable back rest for the,Vuser of the swing, an vimprovedmechanism is provided. This Amechanismconsists ina pair of reciprocable locking orv supportingbars 38, onebeing arranged upon the armrests Vat each end of the body fra-me. TheseVbars extend' laterally lof the. body frame, and each is connected atits forward end'to arelatively'small helical spring 39. The spring 39 isconfined-within a larger helical spring 40, yand both springs aresecured as attl to the foremost of theV posts 8 of the arm rests.v Therear end of each ot the rods38 extends loosely through therear? mostupright S of the arm rest, andis provided with an 'eye or loop 42. Theloops 42 are adapted to receive, hooks 43 secured to the end loars oflthe frame 35,v The hooks 43 are pivoted as at 44 asshown, so that thesame may be readily detached from engagement with the loops whenrequired'.

,Assuming the main or supportingfyframe to be properly suspended rom` aceiling, should it be desired to 'use the apparatus as a porch swing,the back frame 35 is rocked upon its hinges 36 until the lhooks 43 snapinto engagement within the loops 42 at the The revoluble frames in theback frame and body frame are rotated so as to present their slattedsurfaces upward, and, if desired, cushions may be placed upon the backframe and body frame. The locking mechanism for the revoluble frameswill hold the latter firmly against rotating, and the hooks 43 engagedin the eyes 4t2 will hold the said frame in proper upright position. Thecompound springs 39-40 yield slightly to pressure delivered to the backframe, so that a resilient support for the said back frame is provided.When pressure is applied to the hinged back frame, the smaller helicalsprings 39 will be expanded, and excessive pressure upon the said backwill be borne both by the smaller and larger springs 39-40. When it isdesired to use the furniture as a. bed, the back frame is released andallowed to assume the position shown in full lines in Fig. 1. The chain37 will hold the outer end of the frame 35 against passing below thehorizontal plane of the main or supporting frame. The latch or lockingmechanism for the revoluble frames will then be released, whereupon thesaid revoluble frames may be rotated; the spring covered sides of thesaid frames being presented upwardly. Mattresses may then be placed uponthe back frame, and the bed is ready for use.

From the foregoing it is obvious that I have provided 'a convertibleswing which is of extremely simple construction and which may bemanufactured at low cost. The device is also featured by the lack ofintricate or complicated mechanism, and such movable parts as areemployed are so constructed and arranged as to lessen the liability forwear or breakage. Should it be desired, 'suitable means may be employedfor enabling the swinging back frame to be 'held in various angularpositions thus rendering the device adaptable to various positions.

Vhile the present is a disclosure of the preferred embodiment of theinvention, it is to be understood that the invention is not limitedthereto, as various changes in the minor details of construction,proportion, and arrangement may be resorted to if desired withoutdeparting from the spirit of the invention as delined by the appendedclaims.

I claim 1. In a convertible swing, a body frame, a bed frame rotatablymounted in said body frame, a pair of locking bars slidably arranged ateach end of said bed frame and being spaced equidistant from the pivotof the latter, a pair of levers pivoted intermediate their endscentrally of said bed frame, the ends of"said levers being connected oneto each of said locking bars, the body frame being provided with catchesto receive the ends of said locking bars, springs for normally holdingsaid bars projected, and a rod for moving said levers simultaneously.

2. In a convertible swing, a body frame, a bed frame rotatably mountedin said body frame, a pair of locking bars slidably arranged at each endof said bed frame and being spaced equidistant from the pivot of thelatter, a pair of levers pivoted intermediate their ends centrallyI ofsaid bed frame, the ends of said levers being connected one to each ofsaid locking bars, the body frame being provided with catches to receivethe ends of said locking bars, springs for normally holding said barsprojected, a reciprocable rod on said bed frame, and links connectingsaid rod with the said lever.
